T-Mobile Scam Shield vs Whoscall

T-Mobile Scam Shield provides call, text, and web protections for customers on T-Mobile’s network. Incoming calls T-Mobile identifies as likely scams can be labeled Scam Likely, helping customers decide whether to answer or block them. Scam Block can automatically block those calls and can be disabled at any time. Included anti-spam protection covers SMS and MMS, while Safe Web Browsing helps block known malicious or dangerous sites on supported devices and experiences. Calling a number on the Scam Likely list triggers an audible warning through Callback Protection. Network protections work automatically without the app; customers can manage ScamShield in T-Life, turn on Scam Block by dialing #662#, or use My T-Mobile or the T-Mobile app. ScamShield is available for Android and iOS. The free plan is free at no extra cost for T-Mobile customers with qualifying service and a capable device. ScamShield Premium is $4 a month per line and adds categorized call types sent to voicemail, reverse number lookup, and automatic voicemail transcription by text.

Whoscall identifies incoming callers in real time and blocks spam and scam calls on Android and iOS. Its AI checks phone numbers, links, and screenshots against trusted data to flag possible risks. The app also offers Scam SOS, with one-tap access to bank hotlines and online scam reports, and Voice Alerts that warn about suspected scam calls; both features vary by region. Users can report scams and earn points and badges, contributing information to the community. Whoscall says its number database holds more than 2.6 billion entries. The free plan includes caller ID, call blocking, checks for numbers, links, and screenshots, and scam reports and rewards. Paid Individual, Duo, and Family plans add account sharing, database updates, an SMS assistant, ad-free use, and automatic spam blocking; Live Caller ID Plus is limited to iOS 18 or later. Individual costs $27 a year. Business customers can apply for Verified Business Number, which displays a verified company name and logo and requires a minimum six-month purchase.
